Hi TF,
I logged in to my router settings by going to Safari and typing the address of
my router, it will be something like 192.168.0.255. My router has a feature
called “Smart Steering”, which combines Bothe the 2.4 G and 5 G bands, and
shows them as one band. The router then switches between bands as necessary. I
turned off Smart Steering, and then was able to choose either band
independently. Then you can change the channel each band uses in the WIFI
setting of your router.
Hope this helps.

Russell, where and how did you make this band change ?

Hi everyone,
Just thought I’d update the list regarding my issues with my iMac dropping
Internet connections after waking from sleep. I did a bit more Googling and
found a lot of people who had Telus as their service provider were having
issues keeping WIFI connections on the 5G band. I tried switching to the
2.4G band, and the issue was solved. I then contacted Telus to see if we
could figure out why the 5G band kept dropping connection. The person there
changed the channel of the 5G band, and now all is well on both the 2.4G and
5G bands.
Thanks all.

Hi,
Yes, WIFI is at the top. Others have suggested removing all the available
networks and then re-connecting to my network but this didn’t help. Another
suggestion was to delete some network configuration files, but again, this
didn’t fix the issue.
I don’t think this was happening in Sierra. I re-installed High Sierra last
weekend, but this didn’t help. I didn’t do a clean install, so may try that
next.
Thanks for your help.

Hi TF,
Yes, I thought it was you who had the same system.
That’s what I’ve been doing when I get disconnected from WIFI, turn WIFI
off and then back on again. I did try unplugging my modem to reset it,
but that didn’t fix the issue. A Google search finds many others having
this issue, not necessarily with an iMac 2017, but most seem to be
running High Sierra. I just want to make sure it’s not a hardware issue,
but Apple seems not very helpful. I sent them a log file so they could
pass it on the the engineers, and now they want me to try things like
turning off Bluetooth, disabling Handoff, etc. Disabling Handoff did
nothing to fix the issue.
I’ll keep plugging away at this and see if I can get it resolved.
Oh, BTW: Do you know if Apple Care has in-home support? I really don’t
feel like packing up my iMac and taking it to an Apple Store, but it’s
beginning to look like that may be my only option.
Thanks TF.

Russell, I believe I have the same iMac 21.5". I get a few
disconnections, not often, not as often as you are getting.
If it happens I would go into the extra menus into wifi, turn it off
then go back in and turn it on again.
Only other suggestion is to turn your wifi router completely off,
disconnecting the power plug for 30 seconds then turn it on again, this
may reset any errors in the modem.
I am using bluetooth keyboard and mouse is connected though I don't use
it.
I suspect the router/modem and suggest you ensure the problem is not
with that rather than your iMac.
Can you hardwire connect to the router ?

Hi all,
I know at least one other person on this list has the same iMac I just
purchased last June, an iMac 2017. I’m having issues where my WIFI
keeps disconnecting. It shows as being connected when I look at the
WIFI icon in menu extras, but I am not able to connect to the Internet
or send/receive email. It first only happened when waking my iMac from
sleep, but now it seems to be disconnecting randomly, while I’m using
my Mac. I can’t pin down exactly when this issue began. I didn’t have
this issue when I purchased my iMac last June, and I don’t think it
started when I first installed High Sierra, but I think perhaps one of
the High Sierra updates may be the culprit. I’ve been on the phone with
Apple quite a few times with no resolution. On my last call they wanted
me to turn off Bluetooth and see if the issue went away, but I don’t
have access to a wired keyboard, so wasn’t able to do that.
Has anyone else experienced this issue, and, if so, have you found a
fix?
Thanks in advance.
